    Adding R-12 to a R-134A system Question?

    Crazy Question: I have a 1995 honda that uses R-134A refrigerant. I have been retired from the HVAC buisness for 6 years now, and have no 134 left. I went to the auto parts store today, and found an 18 ounce can of 134 is about the same price as crack cocain (I Guess)! So, since I do still have 25 pounds of 12 sitting in the barn with the jug rusting away, can I recover the remaining 134, replace the shaft seal in the compressor, pull a vacum, and recharge with the 12? Or,do I need to repace the oil with a mineral base type? And, will the TXV still give me a satisfactory operating temperature range? I guess the bottom line is has anyone ever done this, and had success with it.
